Scrolling in the Clock time picker -- problem (very slow, step by step)

I've just received my Pre 3. It's a great phone and webOS is a really great OS.

However, there's one thing that's definitely wrong with my software: in the Clock app, when I try to pick a time for an alarm, scrolling over the picker doesn't work as expected, but instead results in an instant (no animation, the length of the finger motion doesn't matter; this looks very "unhealthy") scroll by approx. 30% of the next item.
Therefore, in order to go from 20:00 to 20:10, I need to scroll approx. 30 (thirty!) times. I guess that it's just the first step of the full scroll animation that gets executed -- for some reason, all following "frames" don't get applied.

Does anyone experience this problem as well? Is there any way to reinstall the clock app? Or any other fix?

EDIT: I've just found the reason for my problem: the patch "webOS Scrollbars". Removing it fixes the Clock time picker. However, as it's a great patch, I'd still be grateful for any clue as to how to escape this conflict.
